Powersum is not recognized built-in function name error with Red Gate

I have learned when i was comparing the SQL Server databases from local to live and surprised by error "Powersum is not recognized built-in function name" with SQL Compare tool. I have searched online but no solution for that. I have contacted RadGate support and know that the current version is 6.0, this was the bug in 6.0 version and fixed in later version.
